Residential natural gas leaks can lead to deadly situations and Ameren Illinois is urging customers that if they smell gas to run fast.

Jake Duckett ("DOO-kit"), Public Awareness Supervisor for Ameren says that the biggest concern for folks who detect the rotten-egg smell of gas is static electricity.

Duckett says to call Ameren after you've gotten to safety. He urges customers to not go back in until Ameren has cleared the house.
